基于网络处理器的新型IPv6转发系统的设计与实现

转发与控制分离结构的提出和网络处理器的发展对路由器的扩展性、灵活性、性能具有重要的影响,而IPv6作为下一代互联网协议的核心,是路由器研究的重要对象。简要阐述了基于转发与控制分离结构ForCES的IPv6路由器的系统结构,重点论述了基于网络处理器的IPv6路由器的转发结构、双栈转发系统的流程设计和隧道机制设计的实现,给出IPv6路由器原型系统的实际测试结果。

The Design and Implementation of a New IPv6 Forwarding System Based on Network Processor

ForCES(Forwarding and Control Element Separation)and network processor play very important roles in the router design and implementation.IPv6,the emerging standard for Internet,whose framework has been widely accepted and deployed by the Internet community.In this paper,we design an efficient framework for implementing the Ipv6 router.The approach uses the ForCES protocol to establish communication between the control plane and the data plane.To implement a high performance data forwarding system,the data plane adopts network processor to handle dual IPv4/IPv6 stacks packet forwording,tunneling.We tested the whole prototype system performance by AX4000,the result is excellent.
